In the field of antenna technology a lot of attention has been paid to microstrip antennas (MSA) recently. Many papers are devoted to this problem. But the theoretical part of these investigations has not been carried out sufficiently yet. Nowadays the construction of effective methods of integral equation solution for such problems is very important.

This paper gives a new numerical and analytical method of integral equation solution for linear plane multilayer dielectric substrate vibrators. The analysis of electrodynamic microstrip antenna characteristics is made on the basis of this method.
